Ours is a universe of energy, from powerful jets ejected from black holes to the raw nuclear fury of our Sun. But, the total amount of energy in the universe maintains perfect equilibrium--no more can be added or taken away. Because of this, there are enormous amounts of energy being transferred...electric, thermal, kinetic and magnetic energy are just a few that keep our universe balanced--and create awesome cosmic events and stellar displays.

They sort of sound like the same phenomenon, but Pulsars and Quasars are very different. Pulsars are tiny--only a few miles across--but they spin as fast as a kitchen blender and sweep the sky with beacons of radiation that make them appear to flash on and off. They have unbelievably strong magnetic fields, are more accurate than atomic clocks...and they can even tell aliens just where to find the Earth! Quasars are at the other end of the spectrum. Quasars are huge cores of galaxies with black holes that are called "monsters" and which spit lobes of radiating gas called "DRAGNs." Quasars are so far away, we see them as they were only in the distant past--meaning they existed only in the early universe, when they may have played a major role in the creation of the galaxies themselves.

It may seem like seem like science fiction, but the cosmos isn't just something way out there. Many times in human history, objects or forces from space have changed the course of life on earth. Many believe an asteroid played a role in the fall of the Roman Empire...and millennia earlier another asteroid might have been the "fire and brimstone" that destroyed Sodom and Gomorrah.

What does the Universe sound like? From the sweep of a pulsar, to the deafening roar of our boiling sun this episode explores the undiscovered soundscapes of the solar system, the galaxy, and the entire cosmos. And, is it true that in space nobody can hear you scream?!? Our scientists reveal that there are places in the Universe that prove this sci-fi statement wrong.

It is a fireball in the sky, a bubbling, boiling, kinetic sphere of white hot plasma, exploding and erupting. Its size is almost unimaginable--one million Earths would fit within its boundaries. In this violence is born almost all the energy that makes existence on Earth possible, yet, its full mysteries are only now beginning to be understood. From Sun spots to solar eclipses, solar flares to solar storms, the birth of the sun to its potential death, discover the science and history behind this celestial object that makes life on Earth exist.

Everyone is familiar with the amazing force field and energy weapons from sci-fi movies like Star Wars and Star Trek, but are we just a few years away from having that technology at our fingertips? We'll investigate new, top-secret military weaponry and recent inventions like a new airplane mounted laser cannons from Northrop Grumman that can shoot down enemy planes and shoot nuclear missiles out of the sky.

Robots that think, move like humans and fight our wars--Real Terminators--may now be possible. At leading universities and covert government labs, robots are now being developed in man's image; cyborgs with superhuman strength, machines that may eventually be able to make decisions, even kill on their own. But will these very robots designed to protect us ultimately turn on their masters?

On alien planets, they rain from the sky as scalding iron. On distant moons, even at hundreds of degrees below zero, they slosh around in pristine lakes of methane. They can cover entire planets in miles-deep oceans of electrified hydrogen metal. Or erupt on alien worlds through miles-high geysers. They churn in the interiors of dead stars and even our own planet. They're so rare in the universe, they almost don't exist, but these are the magical liquids of our Liquid Universe.

Warp speed, transporters, wormholes and lasers--they are all staples of science fiction books, movies, and TV shows. But the fantastic world of tomorrow is quickly becoming the futuristic world of today. While you may not be "beaming" to your next appointment any time soon, researchers are preparing for the first tests of a present-day "transporter." And while scientists have long mocked Hollywood's visions of warp speed and faster-than-light travel as prohibited by Einstein's laws, a new generation of physicists continues to rewrite the fundamental rules of the universe. Is there a way around the cosmic speed limit? Maybe... as long as you're prepared to survive a journey through the ultra-high energies of one of the most violent places in the cosmos--the heart of a twisting, swirling vortex that leads either to strange, new worlds... or certain death.

Remember "brick" cell phones, Pac-Man, Rubik's Cube, Sony Walkman, and the first music CDs? Remember all the new and exciting gadgets of the 1980s? Join us as we investigate the transition from Industrial to Information Age--a digital decade dedicated to ergonomics and entertainment. The microchip ushered in an era that revolutionized the way we work, play, and communicate. And we tour Silicon Valley--birthplace of some of the greatest inventions from an amazing time of change, including the modern personal computer. Steve "Woz" Wozniak tells us about the evolution of Apple computers, and we talk to Sony--makers of the Walkman, Betamax, and the first CD players. A visit to the Computer History Museum shows fun technological "artifacts", primitive by today's standards. At Intel, makers of the first microchips, we learn why technology moves at such a fast pace. We also take a ride in a DeLorean DMC-12 sports car--few things moved faster.

"Tiny" weapons may not sound impressive...but small can kill, and it can also be easily concealed. From a pocket pistol used by the police...to a submachine gun wielded by a bodyguard...to a carbine in the hands of an Army Ranger, many of today's most effective weapons are smaller than ever. They can fit in your pocket, fly through the air, even break through walls--tiny weapons are an essential part of battle, self-defense, and spreading terror.

Welcome to the world of sizzling hot oil. First, it's a trip to the fair to discover the secrets behind fried classics such as funnel cakes and churros. And how about some deep fried treats such as frogs legs, and Twinkies and Coke? At Mickey's Diner in St. Paul, Minnesota, get schooled in the tricks of the fried food trade from a master short order cook. See what goes into forging the classic cast iron frying pan, supplying deep fryers for American restaurants, and producing billions of pounds of cooking oil. At Kentucky's World Chicken Festival, witness the world's largest stainless steel frying pan fry up to six hundred chicken quarters at a time. Find out what makes international favorites like British fish and chips, Japanese tempura, and Chinese stir-fry so tasty. Cooking oil is now being deployed as a fuel. Marvel at how San Francisco fire trucks are fueling up on the city's used cooking oil.

Battles over access to lakefront property have made the Great Lakes region the most contested land on the entire map, and even pushed the states to a border war.

With 85% of Americans affiliated with an organized religion, we're a nation of believers, but have we always practiced what we preached?

Utahraptor, Allosaurus, Majungatholus, Albertosaurus and Tyrannosaurus were the elite killers of the prehistoric world. Scientists now know more about these predatory dinosaurs by studying their skeletal designs and using information revealed through CAT scanning technology. Listen as the expert's size up these predators found in numerous worldwide locations and various time periods in their search of the largest killer of all.

Tyrannosaurus rex was the most feared predator on earth--but to one dinosaur, he was prey. A discovery in Montana reveals the broken and fractured bones of a juvenile T-rex, and the teeth of its attacker--Nanotyrannus. As modern crime scene investigative methods are used, paleontologists get an unprecedented look into a 65 million-year-old battle. Modern CAT scanning gives science a never before look into the functions of the brains of Tyrannosaurus and Nanotyrannus. Watch as experts recreate what happened when Nanotyrannus came upon an unguarded juvenile Tyrannosaurus rex.
